EVAPORATING APPARATUS.

SPECIFICATION forming part of Letters `:Patent No. 622,319, 'dated April4, 1899. APPIGMOD led September 27, 1897. Serial No. 653,097. (Nomodel.)

T0 all whom, t may concern:A

.Be it known that I, DAVID AUGSBURGER, a citizen of the United States,residing at Berne, in the county of Adams and State of Indiana, haveinvented-a certain new and useful Improvement in EvaporatingApparatuses, of which the following is a specification.

My invention relates'to a new and useful improvementin evaporatingapparatuses,and has special relation to such devicesfor the cooking ofmolasses, for the purpose of evaporation in thickening molasses, or inmaking sugar and the' like by steam heat, whereby the temperature may beso regulated as to prevent overheating, yet permit a constant actionupon the molasses until the operation is iinished; and a further objectof my invention is to provide for the transference of the material beingtreated from one compartment to another through a series of suchcompartments, whereby the material may be retained in various degreesand transferred from one to the other until the operation is completed;and astill further object-of my invention is to so construct thesteam-compartments ofthe apparatus as to provide for the heating ofcertain of the reservoir-compartments to various degrees to correspondwith the various stages through which the material passes.

NVith these objects in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming part of this specification, in which-Figure l is a plan View of improvement; Fig. 2, a section at .the linethereof; Fig. 3, a section at the line y y of Fig. 2, and Fig. l asection at the line a' a' of Fig. 3.

In carrying out my invention as here embodiedv I provide areservoir-tank A, which may be of any desired size or shape, and thistank is divided into several compartmentsB to B3 by means of thepartitions C, which latter extend crosswise of the reservoir-tank, eachhaving an opening D therethrough,l

' which it may be transferred to adapted to be closed by the slide-'gateE, by which arrangement the material being operated upon may be firstplaced in one of these compartments and there retained until properlytreated for that particular stage, after the next compartment by theopening of the gate E and again treated, from which it may be withdrawnby any suitable means. This tank rests upon the heating-casing F, whichis also divided into a series of compartments G to G4 by the partitionsH and I, the former extending part way across the interior of thecasing, while the latter extend entirely across the same, thus dividingthe casing into a series of double compartments, which are subdivided-by the partitions H, as clearly shown in Fig. 3. The casing F has top.I thereon, through which are a series of holes K, so that while the topsurface is a support for the bottom of the reservoir-tank a largeproportion of the surface of this bottom is exposed to the direct actionof the steam admitted to the heating-casing, thus facilitating thetreatment of the material contained within the tank.

A supply-pipe L, leading from a suitable steam source, runs parallelwith the apparatus and has the branch pipe M and M' leading therefrom,in which are located the valves N, and these last-named pipescommunicate with the compartments G and G3 of the heatingcasing, asclearly shown in Fig. 3, so that when steam is admitted therethrough itwill enter said compartments and pass around the partitions H to thecompartments'G2 to G4, after which it passes from the casing by means ofthe branch pipe P, and suitable valves Q are arranged in the last-namedbranch pipe for regulating the outiow of this steam. After the steampasses from the compartments G2 and G4 to the pipe P it flows fromthence to the compartment G, as indicated by the arrow a, and thisexhaust-steam in circulating through the compartment G serves to heat toa cert-ain extent 'the cold material which may be in the division B atthis time, thereby avoiding the wasting of any heat and preparing theraw material for the next step in the treatment,which takes place afterit has been transferred to the compartment B. The

steam' is entirely exhausted from the appa- IOO ratus through the pipeR', the outflow through which is controlled by a suitable valve.

From this description it is obvious that a slow and continuous heat maybe transmitted to the material contained within the reservoir-tank andthat various degrees of heat may be transmitted to different parts ofsaid tank, so that the molasses or other material contained therein maybe properly treated in its various stages until the operation is finallycompleted, afterwhich it may be drawn from the tank, as before stated.

The waters of condensation which accumulate within the compartments G toGr4 may be drawn therefrom by the drain-pipes R, and these pipes havelocated therein the Valves S for preventing the outflow of the steamfrom t-he colnpartments when this is not necessary.

I have found in practice that molasses may bc so treated as to produce asuperior result by the use of my apparatus than when treated in anyother manner, since it need be never overheated, and yet at all times beheld at the proper temperature for producing the most advantageousresults.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In combination, a reservoir-tank, partitions for dividing the sameinto compartments said partitions having openings therethrough, gatesfor closing said openings, a

heating-casing a perforated top therefor, par'- titions II and I,located within the heatingcasing whereby it is divided into compartmentswhich are subdivided, induction-pipes leading to the heating-casingcompartments and exhaustepipes leading therethrough, substantially asand for the purpose set forth.

2. In combination a heating-casing, partitions I, arranged therein fordividing its interior into compartments, partitions I-I, also arrangedtherein for subdividing said compartments, inductionpipes leading to thecompartments, exhaustpipes leading there from, a valve for controllingthe inflowing and outiiowin g of the steam, drain-pipes leading fromeach of the compartments, Valves connected therewith for regulating theoutflow through these drain-pipes a perforated top for theheating-casing, a reservoir-tank located thereon, partition C, fordividing the tank into compartments, said partitions having holestherethrough and gates for closing said openings, substantially as andfor the purpose set forth.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

DAVID AUGSBURGER.
